Java already has a library that does that. We are not creating the list. We are not abstracting the list as a new data type or implementing it within a new data type, Java has NO templates, or we are not using any templates here, so we are not making this an usable interface that serves multiple types... We are adding NOTHING with this other than to confuse the student and creating useless overhead. If I am wrong, please explain.
